Locking the Device for Sync

When iTunes sends a new song to the device, the device shows a "Sync in progress" screen and when complete, the Music app on the device re-reads the iTunesDB file so it picks up the new song.

To get this behaviour, first start the notification service: 

SOCKET socket;
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);

Now we post a notificaton message to signal that we are going to start a sync: 

AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncWillStart"), NULL);

Next we open the itunes lock file: 

afc_file_ref lockref;
AFCFileRefOpen(conn, "/com.apple.itunes.lock_sync", 2, &lockref);

Now post a notification to say we are going to lock this file, and try and lock it. If the AFCFileRefLock call fails, pause and repeat. 

AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncLockRequest"), NULL);
mach_error_t error = AFCFileRefLock(conn, lockref);

When the file is successfully locked, post another notification, and stop the notification service. 

AMDPostNotification(socket,CFSTR("com.apple.itunes-mobdev.syncDidStart"), NULL);
AMDShutdownNotificationProxy(socket);

Now the sync can proceed, so copy your files across and make the changes to the iTunesDB.

To release the lock, start the notification system again, unlock and close the lock file, and send a sync finished notification message: 

AFCFileRefUnlock(conn, lockref);
AFCFileRefClose(conn, lockref);
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);
AMDPostNotification(socket, &CFSTR("com.apple.itunes-mobdev.syncDidFinish"), NULL);
AMDShutdownNotificationProxy(socket);

NOTE: You may find that starting the notification_proxy service once and once only at the start of your app and using the same socket in calls to AMDPostNotification works better. iTunes opens and closes the notification_proxy regularly, but it appears to be a bit flakey when you open/close it all the time.
